Secure access to and from external means that each host can allocate IPs without any coordination between hosts. The following multi node networking models are supported: Overlay: Encapsulation-based virtual network spanning all hosts EDT-based (Earliest Departure Time) rate-limiting with eBPF for container traffic that is egressing a node. This allows to significantly reduce transmission tail latencies for applications and to avoid locking
